Question 11

A customer's database application is running on an OceanStor V3 storage system. The database uses
six LUNs. The customer wants to migrate data from the OceanStor V3 storage system to an OceanStor
18000 series storage system based on the functions provided at the storage side. Which statements
are true?
(Multiple Choice)

• A. If you use the HyperReplication function to migrate data on multiple LUNs used by the database, you must add multiple remote replication tasks to one consistency group.
• B. The HyperReplication function can implement online data migration.
• C. After data is migrated using HyperCopy or HyperReplication, services can be started without the need to make any configuration on the host.
• D. If data is migrated using HyperCopy, the migration speed can be dynamically changed during the copy process.

Question 12

Which statement about SmartMigration functions is false during a SmartMigration-based migration?

• A. If multiple LUNs are used by a service, the LUNs must undergo a consistency splitting after the migration.
• B. If multiple LUNs are used by a service, consistency splitting cannot be performed before stopping services.
• C. For higher migration speed and storage performance, a migration task can be deleted as soon as it is completed.
• D. It is recommended to perform consistency splitting in off-peak hours.

Question 13

Question 15

An application's peak write throughput is 10 MB/s, average write throughput is 280 KB/s, average
write I/O size is 4 KB, and the network bandwidth utilization rate is 70%. If OceanStor V3 storage
systems are used to implement data disaster recovery based on asynchronous replication,
